BALINGI- PRESS.

SPECIFICATION forming part of Letters Patent No. 651,830, dated June 19, 1900.

Application filed October 3, 1898.

To aZZ whom it may concern:

Be it known that I, THOMAS J. CORNING, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and Stateof Michigan, have invented certain new and useful Improvements in Baling- Presses, of which the following is a specification.

This invention relates to improvements in hay-presses and presses for similar purposes.

As heretofore constructed hay-presses or presses for baling straw have been cumbersome in the extreme if theypossess sufiicient power to operate efficiently, and they have also been so constructed that there was-considerable variation in the power required to properly operate the same,and for a moderate size they lack sufficient speed.

The objects of this invention are, first, to provide a simple, compact, and efficient con-- struction which can be easily operated inside of abarn of ordinary size; second, to provide a new and improved mechanism for exerting power on the plunger of hay-pressesor similar machines; third, to provide an improved trip for use in such press to release the mechanism to allow the plunger to be returned by springsor otherwise; fourth, to provide, in connection with a structure of this kind, improved means of recoiling the chain when the plunger is returned to its initial position; fifth, to provide improved means of retaining the follow-board inposition in a hay-press, whereby the springs for holding the dogs are placed outside and easily accessible; sixth, to provide an improved construction for applying a brake to'the plunger to prevent its rebound afteritis released and withdrawn, and, seventh,'to provide an improved combination of eccentrics for delivering power to a press or for similar purposes. Other objects will definitely appear in the detailed description to follow. I accomplish these objects by the devices, means, and mechanism described in this specification.

Theinvention is clearly detined,and pointed out in the claims.

The structure embracing my invention is fully illustrated in the accompanying drawings, forming apart of this specification, in which Figure 1 is a detail sectional elevation of a $eria1No.692,565. (N0 model.)

Fig. 10 is an enlarged detail sectional view taken on line 10 10 of Fig. 9. k

In the drawings all the sectional views are taken looking in the direction of the little ar rows at the ends of the section-lines, and in the drawings similar letters of reference refer to similar parts throughout the several views. Referring to the lettered parts of the drawings,"A represents the main frame of the haypress, which is in the usual form, except in the modifications and changes hereinafter described, and it has the usual bale-holder, only I a portion of which is shown in the drawings.

The press is carried on suitable wheels, which can be let down into the ground where the press is used in open air or can be removed to lower the press when it is usedon a barnfioor. Within the press is a plunger D, to

which is rigidlysecured a pitman D, consistin g of a pair of bars, preferably of steel. The

rear ends of the bars are connected by pin f,

to which is: attached the chain I for actuating the same. The plunger being secured rigidly to the pitman, provision is made for variation of the movement of the pitman by providing suitable guides T for the plunger in A slide the side of the frame of the press. N is provided to travel in the guides and is secured to the head of pivot N, (see Figs. 2, 4, and 5,) which permits the head to swing slightly to accommodate the movements of the pitman. This enables a very short head to be used, thus securing compactness. The head is provided with means for returning it to the initial position, and the sides of the press are adapted to be drawn slightlytogether, a space h being left for that purpose in t the frame by a bolt 9 through the press and projecting in from the opposite sides of the,

press. Suitable notches t' are made in the plunger for it toipass the dogs. Blade-springs,

P are secured to the outside to hold the dogs in engaging position. This enables an easy replacing of the parts when necessary. Other forms of springs are possible.

Supported in the rear part of the press, by hooked bolts v through plates 'm, are tubes G, containing springs r, with rods 1", to which are 7 connected chains t to return the plunger-head to the initial position. The length of the chains can be easily adjusted, as they are securedtothe head by hooks t, adapted to engage the links of the chain.

Supported on. shaft E, which has suitable bearings 11 inthe rear portion of the frame, is an eccentric E, which'is provided with a suitable face for receiving the actuatingchain I. The chain I extends around the'eccentric, but is not secured thereto, but embraces the cross-pin f at the rear end of the pitman D. The face of the eccentric is conformed and grooved to receive the chain I, and a small notch is formed at the point nearest the shaft to receive the pin f of, the pitman to'enable power to be delivered directly from the shaft E, and thus relieve much of the heavy strain on the chain, making it possible to use comparatively-light chain in this relation, though by dispensing with the notch the same would still be very efiective.

Supported by suitable stirrups or yokes H to the rear of .themain frame is a pairof timbers or beams H, extending rearwardly from the machine. A suitable vertical shaft K,

with, an eccentric K, is located on these beam-s. These two parts can be formed integral, as shown in the drawings, or can be i normally outward by a spring e. side of the dog a is beveled and is adapted to "base which carries the eccentric. .tion the dog a strikes lug or ear a, which ing the hay-into bales. ;tinues to travel-the eccentric swings down made separate and the parts united. Around this eccentric isaring which has an eye S, to which chain L is secured. A rod L extends from the chain L to aslide J. The slide .I is carried by suitable guides R R. A rod 1 is also connected to the slide and extends forwardly, terminating in a chain 1, which embraces the eccentric E, as heretofore described.

Supported on a suitable guide on the ec- 'centric K is a sliding dog Ct, which is held The front strike against a lug or ear a, secured to the In operapushes it back and releases the ring, allowing it to swing back around the eccentric.

The usual sweep M for attaching the horse is provided on the upper end of shaft. K.

. Any suitable power could be applied.

Having thus described the various parts of my improved hay-press, I will briefly indicate their operation.

In the operation of my improved hay-press the hay is fed into the hopper F as the horse operates the machine from the sweep M. The

[plunger being withdrawn at the time as the horse moves aroundv the power, the eccentric E, being up, is actuated quickly, so that the plunger moves quickly on the start, press As the horse conuntil the pitman D approaches close to the shaft E, carrying the eccentric E, when of 1 course the greatest power is delivered. The

horse traveling around winds. up the chainL on the eccentric K, and when the plunger is 1 near the end of its stroke the chainL is nearest the center of therotationof the eccentric K, so it will be observed that the power at that point is applied to the greatest advantage,

the leverage in both eccentrics being at the heaviest point. As eccentric E swings down (see Fig. 3) the cross-pinf is engaged by a little notch therein, so that in finishing the stroke the pressure is delivered largely from this notch and is almost entirely taken up by the shaft, and much of the strain on the chain is relieved. It would be possible, however, to provide a chain strong enough within convenient limits todispense with the notch. As the horse travels around the sweep the-sliding dog a comes in contact with the ear or lug A and is driven back and releases the ring S. This releases the entire power mechanism from acting on the plunger. The plunger being so released is immediately'withdrawn. by

.the springs r, connected by the rod r and chain T to' the plunger.

act as a spring to throw the plunger back. When the plunger is thrown back either by the springs or other means, (for other means might be provided, though not so desirable,)-

it passes between the side walls, which are slightly drawn together by the bolt g, and is wedged between the same and any rebounding is prevented. The operation is of course continued till a bale of the required size is produced, when it is tied up in the usual way,

I have fully described the structure and operation of my improved hay-baling press and wish to state that many of its details can be varied without departing from my-invention, though I believe that the exact construction which I have shown will be found the best in all its details, taking into consideration expense of material and labor in manufacturing and efficiencyof the operation of the machine. YVhile the slide J, with its guides R R, is preferred by me, I am aware that other guides may be easily substituted, and, in fact, the machine would operate with no guides at all at that point. I have the pitman D double to engage the opposite side of the eccentric E to serve as a guide. This is a most efiicient means and worthy of a patent claim, though I am aware that other means might be adopted and still secure the valuable cffects of the remaining devices. The incased springs r are preferred by me, though I am aware that other spring connections could be provided for returning the plunger and that this might be done by a weight, or other means might. be provided for returning it by power. The spring, however, as I have it shown is desirable on account of the quickness of its action, its simplicity, and its great efiiciency. In place of chain and rod connections, as I have shown,other connections might be adopted which would operate the machine, though the chains are preferred on account of the facility with which they engage the eccentric to actuate the same and for other obvious reasons.

1 have shown my machine all connected together in practically a single frame. It would be possible to provide suitable anchors and anchor the horse-power separate from the press should it for any reason be desirable so to do. This would materially interfere with the compactness and portability of the machine, however. The press could be operated by other power.
